LUBRHCATING=CAN.

SPECIFCATION forming part of Letters latent No. 696,501, dated April 1, 1902..

Application filed December 17, 1901. Serial No. 86,218. (No model.)

To @l whom it may concern:

Be it known that I, JULIUS SCHMIDT, a citizen of the United States, and a resident of Ludlow, in the county of Kenton and State of Kentucky, have invented certain new and useful improvements in Lubricating-Gans; and I do declare the following to be a clear, full, and exact description thereof, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form also a part of this specification.

This invention relates to improvements in lubricating-cans in form of hand-Oilers used for applying lubricatingoil and combining in one implement the vessel or can which contains the oil and the means for causing the same to discharge and for guiding and directing such discharge to the particular parts and locations where the lubricant is to be applied.

The invention consists of certain improvetments in details of construction, as hereinafiter shown and described, and whereby the manufacture of the entire device is simplified and its construction rendered more reliable and compact.

In the following specification, and particularly pointed out .in the claims at the end thereof, is found a full description of the invention., together with its manner of use, parts, and construction, which latter is also illustrated in the accompanying drawings, in which- Figure 1 shows in side elevation the oiler in use. Fig. 2 is another side elevation of the same, showing it in a plane viewed at right angles to the view of the preceding figure. Fig. 3 is part of a vertical central section of the oiler viewed on a plane as shown in the preceding ligure. Fig. 4E is part of an elevation with the side partly broken away. Fig. 5 is a top view of the lower part of the oiler. Fig. 6 is a vertical section through the vented plug, enlarged. Fig. 7 is an enlarged detail view of the combined spoutcoupling and valve-seat,the'same being shown in vertical section. Fig. Sis a detail view of the rock-shaft and connected rocker-arm whereby the valve in the spout is operated.

The lower part of the oiler serves as a reservoir to hold the oil, being the oil-can proper, and vis of cylindrical shape as to its lower part 10 and of conical shape 1l above the same. 12 is the spout connected at the apex of this conical part, with its discharge-nozzle 13 straight or curved, as shown in Fig. 1.

1a is the handle whereby the implement is held while used in various positions to apply oil-as, for instance, shown in Fig. 1. Immediately above it is the fill-inlet, the opening 15 being in the conical part 11 and surmounted by a fill-tube 16, the upper end of which is. closed by a screw-plug 17. For its manipulation this latter is provided with a knob 18, both being of sheet metal and hollow. The knob is made in two sections joined to each other by a seam a, the joining edges being so shaped as to merely overlap each other sufficiently to keep the upper section in place on the lower one to hold this plug closed and to prevent the outlet from becoming open. This seam is, however, not sufficiently tight to exclude air, and by' admitting the same the plug as so constructed provides for the necessary vent to permit the oil to discharge from the nozzle. To prevent oil from entering this hollow plug and its knob when the device is held in a positionas, for instance, shown in Fig. 1 whereby it would obstruct ingress of air through the open seam at a and also ooze out therethrough, I provide a hollow conical eX- tension 19, depending from the under side of the hollow screw-plug and in open communication therewith. The air admitted through seam a escapes into the interior of the reservoir through a small opening at the pointed end 21 of this conical extension. This opening, while sufficiently large for air-admission, does not permit escape of oil, which, being thick and viscid, does not readily enter such a small opening. Escape of oil from the nozzle when no discharge is intended is normally prevented by a valve 22, mounted at the upper end of arod 23 and seated against a valveseat 24. This latter is contained in a castmetal member, serving at the same time as a coupling 25 between spout and nozzle for holding one to the other. There the nozzle is removably connected to permit interchange with other ones of diiferent shape or size or removal for cleaning, this coupling consists of two complementary parts, as shown in Figs. l and 3, and joined by a scrcwconnec- IOO tion-one part being attached to the end of the spout, the other to the contiguous end of the nozzle. Valve-seat 24 is contained in the part attached to the spout. When the nozzle is not detachable, said coupling is in one piece only, as shown in Figs. 2 and 7, and serves then simply as a soldering-coupling, uniting spout and nozzle, since these two parts being of sheet metal are not readily made in one piece.

Valve 22 is held normally to its seat by a spring 26, attached with one end to theinside of the can and with its other to a rockerarm 27, projecting from a rock-shaft 28 and to which rocker-arm rod 23 attaches, there being a lug 29 provided for such purpose. Rock-shaft 28 is supported in two bearings 3l and 32. The first, intended to support the inner end of the rock-shaft, is attached to and projects from the inside of the conical part 1l of the oil-reservoir. The other, being a tube, is attached opposite thereto, also to part ll, passing through the same, however, and projecting in wardly,as well as outwardly, therefrom.

33 is a shoulder on the rock-shaft, which may also be produced by reducing part of such shaft, and this latter is kept in position lengthwise by this shoulder and by arm 27, which bear each against the opposite inner ends of the shaft-bearings, thus holding the shaft immovable lengthwise, but free for rotation- The outer end of shaft 28 projects beyond tube 32, and the operating-lever handle 34 is affixed to this projecting end. That part of the shaft within tube 32 is closely fitted thereto,and the contacting surfaces between shoulder 33 and the inner edge of tube 32 are fitted to each other by means of a ground joint, so that any escape of oil at the point where the rock-shaft passes to the outside is prevented without the Vuse of stuffing-boxes, packing, or washers, all of which parts add to the manufacturing expenses and are not effective toward preventing leakage unless constantly attended to and repacked. There may also be a ground joint at the outside and between the outer end of tube 32 and the hub of lever-handle 34, which latter serves to hold the members forming this ground joint in contact. The shaft is also held lengthwise in position between shoulder 33 and the leverhandle 34. It will now be seen that for purposes of effecting discharge of oil it is only necessary to depress the lever-handle, (see dotted lines in Figs. 2 and 3,) which is done by the thumb of the hand having hold of handle 14 of the implement, as shown in Fig. I, and the parts are so located that this latter handle serves as a stop, as shown in dotted lines in Fig. 2, to any further movement of operating-handle 34 as soon as the same has been suiiciently depressed to open valve 22. This operation and opening of the valve need not take place until the nozzle is placed at the exact pointwhere the oil is wan ted, so that any premature discharge of oil from the tipped can is prevented and deferred until the nozzle is in proper position. The discharge may be instantly stopped equally as well, notwithstanding the tipped position of the can, and does not continue until this latter is restored to its upright position, all of which saves oil and prevents spattering of the same over parts and places where it is not wanted.

In the practical construction of this device the inner end of shaft 28 must be placed rst into the previously-attached bearing 3l, and the other bearing 32 cannot be permanently connected to the conical part ll until the shaft is in position within the two bearings.

Having described my invention, I claim as new I. In a hand-oiler, the combination vof an oil-reservoir, an outlet-spout with a dischargenozzle, a valve to control such discharge, an inlet-opening, a lill-tube surmounting the same, a hollow screw-plug to close this latter having a hollow knob consisting of two sections on its upper side and a hollow conical extension on its under side which extends into the oil-reservoir, all these parts in open communication with each other, an air-inlet between the two sections of the hollow knob and an additional one in the lower pointed end of its conical extension.
